ZALDIVAR, D. et al. A new approach in copolymerization: Monte Carlo method for the reactivity ratios calculation in copolymerization of furfuryl acrylate with 2-hydroxyethyl methacrylate. Polímeros [online]. 1999, vol.9, n.1, pp.35-40. ISSN 0104-1428.  https://doi.org/10.1590/S0104-14281999000100005.

Copolymers of furfuryl acrylate (A) with 2-hydroxyethyl methacrylate (H) were prepared by free radical copolymerization in DMF solution at 50°C, using 2,2'-azobisisobutyronitrile (AIBN) as initiator. The reactivity ratios of both monomers were calculated according to the general copolymerization equation using the Fineman-Röss and Kelen-Tüdos 1inearization methods, as well as the Tidwell-Mortimer non linear least-squares treatment and the Monte Carlo random method. The reactivity ratios obtained were rA = 0.93 and rH = 1.42. Similar results were obtained by both, the Monte Carlo and the non-linear least squares methods. The microstructure of copolymer chains based on the first order Markov statistics is described.

Palavras-chave : Reactivity ratios; copolymerization microstructure; furfuryl acrylate; 2-hydroxyethyl methacrylate.
